A subject based repository of life sciences journal literature as well as materials deposited by individual authors. This is an extensive and expansive resource for researchers in the bioscience, biotech and biomedical related disciplines. The citations database PubMed links to full-text materials within PMC. Thanks to a NLM digitisation activity older journal content is being made freely available, back to the early 1900s in some cases. Currently 250 journal titles are included within the site. It is possible to register for an update email to ensure notification when new journals are added to the PMC collections. The size value given is the number of author submitted manuscripts.
